ipv6: Neighbour table overflow

If syslog starts complaining about neighbor table overflow  then some limits need to be increased.

Current values:

grep . /proc/sys/net/ipv6/neigh/default/gc_thresh*

Add to sysctl.conf

net.ipv6.neigh.default.gc_thresh1 = 512
net.ipv6.neigh.default.gc_thresh2 = 2048
net.ipv6.neigh.default.gc_thresh3 = 4096

Reload sysctl parameters

sysctl -p
